Secure communication routing for remote devices

ABSTRACT

A security system that provides for obfuscating the sending entities, receiving entities, and/or routings (e.g., host entities that are routing the communication and the path through which the communication is sent) without the need to encrypt the foregoing. The packets for a communication may include a datagram packet portion, an IP packet portion, and a routing packet portion and may be signed with a signature using a pre-shared key (e.g., a wheat signature or a chaff signature). Therefore, the actual datagram packet, IP packet, and/or routing packet may have the actual information or may have imitation information. Only the systems that have the pre-shared key are able to determine what are the wheat packets and what are the chaff packets such that the correct sending entity, receiving entity, and/or hosts routing the communication are able to determine the correct entities and/or the routing.

FIELD

The present invention relates to a security system, and more particularly to a security system that allows a system to send communications and obfuscate the sending entity, receiving entity, and/or the routing of the communication without encryption.

BACKGROUND

In order to send secure communications, typical communications are encrypted utilizing a session key. Only the parties with the session key are able to read the communications, the sending entities, the receiving entities, and/or the routing of the communications. Should any party have access to the session key, the parties can review the communications, the sending entities, the receiving entities, and/or the routing of the communications that were encrypted using the session key.

SUMMARY

The following presents a simplified summary of one or more embodiments of the present invention, in order to provide a basic understanding of such embodiments. This summary is not an extensive overview of all contemplated embodiments, and is intended to neither identify key or critical elements of all embodiments nor delineate the scope of any or all embodiments. Its sole purpose is to present some concepts of one or more embodiments of the present invention in a simplified form as a prelude to the more detailed description that is presented later.

Generally, systems, computer products, and methods are described herein for a security system that provides for secure communication from a remote system operating on an unsecure network without the need for encrypting the packets related to the communication. The packets for the communications are sent over the network in clear text, which are readable by any systems on the network; however, only the systems that are authorized are able to determine what packets are the correct packets and what packets are the imitation packets. Moreover, a remote secure network may be utilized such that any system operating on an unsecure network may send packets through the remote secure network in a randomized routing in order to aid in hiding the systems sending and receiving the packets and the relays through which the packets are being sent.

Furthermore systems, computer products, and method are described herein for a security system that provides for obfuscating the sending entities, receiving entities, and/or routings (e.g., host entities that are routing the communication and the path through which the communication is sent) without the need to encrypt the sending entities, receiving entities, and/or routings. The packets for a communication may include a datagram packet portion, an IP packet portion, and a routing packet portion and may be signed with a signature using a pre-shared key (e.g., a wheat signature or a chaff signature). As such, the wheat packets for the communication may include the actual datagram packet, IP packet, and routing packet. Moreover, the chaff packets for the communication may include the imitation datagram packet, IP packet, and/or routing packet. As such, anyone of the chaff datagram packet, IP packets, and/or routing packets may include imitation sending entity, receiving entity, and/or routing information in order to obfuscate the actual sending entity, receiving entity, and/or routing information. Only the systems that have the pre-shared key are able to determine what are the wheat packets and what are the chaff packets such that the correct sending entity, receiving entity, and/or hosts routing the communication are able to determine the correct entities and/or the routing.

Embodiments of the invention comprise systems, computer implemented methods, and computer program products for securely sending communications using a plurality of packets. The invention comprises creating one or more wheat packets for a communication, each of the one or more wheat packets comprise a wheat datagram packet portion, a wheat IP packet portion, and a wheat routing packet portion. A wheat signature is attached to at least one field within the wheat datagram packet portion, the wheat IP packet portion, or the wheat routing packet portion, wherein the wheat signature is created using a pre-shared key. One or more chaff packets are utilized for the communication, each of the one or more chaff packets comprise a chaff datagram packet portion, a chaff IP packet portion, and a chaff routing packet portion, and wherein a chaff signature is attached to at least one field within the chaff datagram packet portion, the chaff IP packet portion, or the chaff routing packet portion. The plurality of packets, which comprise the one or more wheat packets and the one or more chaff packets, are routed through one or more hosts. The one or more hosts receive the plurality of packets for the communication. The one or more processing devices of the one or hosts are configured to execute computer readable code to determine a validated signature for each of the plurality of packets. The one or more chaff packets are identified when the at least one field of the chaff datagram packet portion, the chaff IP packet portion, or the chaff routing packet portion has the chaff signature that fails to meet the validated signature. The one or more wheat packets are identified when the at least one field of the wheat datagram packet portion, the wheat IP packet portion, or the wheat routing packet portion meets the validated signature. Thereafter a routing is determined for the one or more wheat packets. One or more other systems are prevented from determining a sending entity, a receiving entity, or the routing for the communication without identifying the one or more wheat packets or the one or more chaff packets from the plurality of packets using the validated signature.

In further accord with embodiments, the invention further comprises receiving the pre-shared key for the communications.

In other embodiments of the invention, determining the validated signature comprises replicating a received signature for the plurality of packets, wherein the received signature is the chaff signature of the one or more chaff packets or the wheat signature of the one or more wheat packets.

In yet other embodiments of the invention, the received signature comprises a message authentication code (MAC), and wherein replicating the MAC comprises using the pre-shared key and an algorithm to create the validated signature.

In still other embodiments of the invention, the algorithm is a pre-shared algorithm that is shared with the system for the communications.

In other embodiments of the invention, replicating the received signature further comprises using at least a portion of the plurality of packets to determine the validated signature.

In further accord with embodiments of the invention, one or more wheat signatures are attached to at least two of the wheat datagram packet portion, the wheat IP packet portion, and the wheat routing packet portion.

In other embodiments of the invention, one or more chaff signatures are attached to at least two of the chaff datagram packet portion, the chaff IP packet portion, and the chaff routing packet portion.

In still other embodiments of the invention, one or more chaff signatures are attached to the chaff datagram packet portion, the chaff IP packet portion, and the chaff routing packet portion.

In other embodiments of the invention, the at least one field to which the wheat signature or the chaff signature is attached is a sequence number field of the wheat datagram packet portion or the chaff datagram packet portion.

In further accord with embodiments of the invention, the at least one field to which the wheat signature or the chaff signature is attached is an acknowledgement field of the wheat datagram packet portion or the chaff datagram packet portion.

In other embodiments of the invention, the at least one field to which the wheat signature or the chaff signature is attached is one or more flag fields of the wheat datagram packet portion or the chaff datagram packet portion.

In yet other embodiments of the invention, the at least one field to which the wheat signature or the chaff signature is attached is a checksum field of the wheat datagram packet portion or the chaff datagram packet portion.

In still other embodiments of the invention, the at least one field to which the wheat signature or the chaff signature is attached is an identification of the wheat IP packet portion or the chaff IP packet portion.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

Embodiments of the invention will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident; however, that such embodiment(s) may be practiced without these specific details. Like numbers refer to like elements throughout.

Systems, methods, and computer program products are described herein for a security system that provides for secure communication from a remote system operating on an unsecure network without the need for encrypting the packets related to the communication. The packets for the communications are sent over the network in clear text, which are readable by any systems on the network, however, only the systems that are authorized are able to determine what packets are the correct packets and what packets are the imitation packets. Moreover, a remote secure network may be utilized such that any system operating on an unsecure network may send packets through the remote secure network using a randomized routing in order to aid in hiding the systems sending and receiving the packets and the relays through which the packets are being sent. Furthermore, the security system may provide for obfuscating the sending entities, receiving entities, and/or routings (e.g., host entities that are routing the communication and the path through which the communication is sent) without the need to encrypt the sending entities, receiving entities, and/or routings. The packets for a communication may include a datagram packet portion, an IP packet portion, and a routing packet portion and may be signed with a signature using a pre-shared key (e.g., a wheat signature or a chaff signature). As such, the wheat packets for the communication may include the actual datagram packet, IP packet, and routing packet. Moreover, the chaff packets for the communication may include the imitation datagram packet, IP packet, and/or routing packet. As such, anyone of the chaff datagram packet, IP packets, and/or routing packets may include imitation sending entity, receiving entity, and/or routing information in order to obfuscate the actual sending entity, receiving entity, and/or routing information. Only the systems that have the pre-shared key are able to determine what are the wheat packets and what are the chaff packets such that the correct sending entity, receiving entity, and/or hosts routing the communication are able to determine the correct entities and/or the routing.

FIG. 1 illustrates a network security system environment 1, in accordance with embodiments of the present disclosure. As illustrated in FIG. 1, one or more organization systems 10 are operatively coupled, via a network 2, to one or more user computer systems 20, one or more security systems 30, one or more third-party systems 40, and/or one or more other systems (not illustrated). In this way, the security systems 30 (in coordination with the user computer systems 20 and/or other systems on the network) may be utilized to create secure communications over the network 2 without the need to encrypt all or a majority of the communications between the systems on the network 2. As will be described herein, the security systems 30 and/or other systems described herein may utilize security signatures (e.g., keys, MACs, algorithms, and/or the like) attached to packets to allow a receiving system to identify the valid packets for a communication. For example, the security systems 30 and/or other systems (e.g., user computer systems 20) may create and/or assign one or more keys (e.g., pre-shared keys, such a global network keys, content keys, segmentation keys, or the like) and one or more algorithms (e.g., pre-shared algorithm, or the like). The one or more keys and the one or more algorithms may be utilized to create message authentication codes (MACs) for each of the packets being sent, in particular, wheat packets, as will be discussed herein. Moreover, chaff packets (e.g., unrelated real packets, imitation packets, combinations thereof, or the like) and wheat packets (e.g., real packets, or the like) may be used when sending communications. Any receiving system must be able to identify the security signature in order to determine what packets are wheat packets to determine the communication, receiving entity, sending entity, and/or routing, and what packets are chaff packets that should be discarded. For example, each receiving system may have the key (e.g., pre-shared key) and the one or more algorithms in order to determine what MAC attached to a packet is valid, and thus, identify what packets are wheat packets and what are chaff packets that can be discarded (e.g., a technique that may be described as winnowing). The wheat packets can then be identified as the legitimate communication. In addition, the communication may be broken up into a plurality of wheat packets before the security signature is added, and as such, the receiving system may also have to reassemble the plurality of wheat packets together in order to identify the communications. While security is achieved through keys, algorithms, splitting packets, or the like, the messages themselves, the sending entity, the receiving entity, and/or routings are sent over the network 2 without any encryption, as will be described in further detail herein.

The communications that may utilize the embodiments of the present disclosure, may include any type of communication such as, but not limited to, communication related to a computer system trying to access a network, communications between segmented computer systems within a network trying to communicate with other computer systems within the same segment, computer systems trying to communication with systems on other networks, or the like. The communications may relate to interactions, accessing data, running applications, sending messages, or the like, as will be discussed in further detail herein.

The network 2 may be a global area network (GAN), such as the Internet, a wide area network (WAN), a local area network (LAN), or any other type of network or combination of networks. The network 2 may provide for wireline, wireless, or a combination of wireline and wireless communication between systems, services, components, and/or devices on the network 2.

As illustrated in FIG. 1, the one or more security systems 30 may have computer-readable instructions 38 stored in the one or more memory components 36, which in one embodiment includes the computer-readable instructions 38 of one or more security applications 37. In some embodiments, the one or more memory components 36 include one or more data stores 39 for storing data related to the one or more security systems 30, including, but not limited to, data created, accessed, and/or used by the one or more security applications 37.

In some embodiments, the one or more security systems 30 may be operated by the organization (e.g., be one of the one or more organization systems 10), or may be operated by a third-party on behalf of the organization.

Moreover, as illustrated in FIG. 1, the one or more third-party systems 40 are operatively coupled to the one or more organization systems 10, the one or more user computer systems 20, the one or more security systems 30, and/or the one or more other systems, through the network 2. The one or more third-party systems 40, and/or other like systems have components the same as or similar to the components described with respect to the one or more organization systems 10, the one or more user computer systems 20, and/or the one or more security systems 30 (e.g., one or more communication components, one or more processing components, and one or more memory devices with computer-readable instructions of one or more third-party applications, one or more datastores, or the like). Thus, the one or more third-party systems 40 communicate with the one or more organization systems 10, the one or more user computer systems 20, the one or more security systems 30, and/or each other in same or similar way as previously described with respect to the one or more organization systems 10, the one or more user computer systems 20, and/or the one or more security systems 30. The one or more third-party systems 40 may comprises the systems and applications that are trying to access the network 2 (e.g., as authorized parties, unauthorized parties, or the like). As such, in some embodiments the third-parties may be unauthorized third-parties that are trying to misappropriate communications between authorized systems on the network 2. In some embodiments, the third-parties are authorized to access the network 2 for various reasons (e.g., to perform maintenance, enter interactions, support the organization systems or the like). In still other embodiments, the third-parties may be external systems on external secure networks that aid in allowing authorized users 4 (e.g., users that are located outside of the network 2, such as out of the country) to access the network 2 from abroad.

The one or more other systems (not illustrated) may include the systems, and components thereof, for allowing communications between the systems (e.g., intermediaries that act as gateways, APIs, or the like to allow communication between the systems).

FIG. 2 illustrates a network environment 100 in which multiple entity computer systems (e.g., user computer systems 20), and entities (e.g., users 4) associated therewith, communicate with each other and other systems, including, but not limited to the security systems 30, the organization systems 10, or the like. The communications between the systems 20 may be secured communications, as will be described in further detail below. The network environment 200 may be any type of network 2, such as an internal network, external network, cross-organizational network, or any type of network of entity computer systems. In some embodiments the network may be a single network; however, in some embodiments while the network is a single network, it may have two or more segmented networks that may be regulated based on signatures (e.g., MAC that are created and identified using keys and/or algorithms) attached to packets. As such, even though a system may be able to access the network 2, the system may not be able to communicate with other systems on the network (e.g., the system may not be able to create signatures that other systems can validate and/or the system may not be able to read signatures created by other systems on the network 2). As illustrated in FIG. 2, the network 2 may comprise a first entity computer system 20 a, a second entity computer system 20 b, a third entity computer system 20 c, a fourth entity computer systems 20 d, up to an n^(th) entity computer system 20 n. As further illustrated in Figures, the computer systems 20 a to 20 n ^(th) may correspond with entities, such as a first user 4 a, a second user 4 b, a third user 4 c, a fourth user 4 d, an nth user 4 n, or the like. As will be discussed in further detail herein with respect the systems on the network 2, the systems may send and receive secure communications using wheat packets and chaff packets.

The present disclosure provides an improved way for sending communications between systems in secure way in order to restrict unauthorized third-party systems from accessing the network 2, and if they gain access to the system, to restrict such third-party systems from being able to intercept and identify the correct communication, sending party, receiving party, and/or routing to misappropriate the communications (e.g., content, metadata, or other information that may be identified from the packets. Furthermore, the present disclosure provides an improved way to allow for external users (e.g., travelers) to other countries operating outside of the network 2 (e.g., home network) to access the network 2 from an external unsecured network and to communicate with the systems on the network 2. In some embodiments, the users 4 operating on an unsecured network 3 may send communications through a remote secure network 5, which in addition to using wheat packets and chaff packets, may also obfuscate the sending entity, the receiving entity, and/or the routing of the packets. The present disclosure also allows for providing segmentation of the systems on the network 2 using different signatures (e.g., different keys and/or algorithms) to only allow sub-sets of the systems on the network 2 to communicate with each other.

The present invention utilizes and expands upon a chaffing communication technique that is utilized to provide confidential communication between systems on a network 2. Communication between systems may involve the sending systems creating and/or sending packets to the receiving system. The packets may comprise wheat packets (e.g., authorized packets, valid packets, or the like) and chaff packets (e.g., unauthorized packets, imitation packets, or the like), and the receiving system authenticates the signatures on the packets and separates the chaff packets from the wheat packets. The wheat packets may include the actual communication (e.g., message, process instructions, file, data, or the like) and/or portions thereof, while the chaff packets are the imitation communication and/or portions thereof.

The packets (e.g., wheat and chaff packets) are sent with authentication in form of a signature. The signature may be any type of secure signature that may be used to determine the packets that are wheat packets, how to assemble the wheat packets (if necessary), and/or what and/or how to use one or more keys and/or one or more algorithms (if necessary) in order to read the packets. For example, the signature may be an MAC that is created using a key (e.g., a pre-shared key), a MAC algorithm, and in some embodiments the packet itself (e.g., content of the communication, serial number of the wheat packets, both of the forgoing, and/or the like). For example, the key and at least a portion of the packet are inputs into the MAC algorithm, and the output of the MAC algorithm is the MAC that is attached to the wheat packet. The security system 30, and/or individual agents (e.g., pre-loaded applications, or portions thereof) that are located on each system, may be responsible for creating the wheat packets with the signature (e.g., authorized signature) and the chaff packets with an imitation signature, as will be described herein in further detail.

The receiving system may use the signature in order to determine what packets are wheat packets and what packets are chaff packets that can be discarded. For example, a receiving computer system receiving the packets (e.g., wheat packets, chaff packets, sub-portions thereof, or the like) may only be able to identify the correct communication using the key (e.g., pre-shared key) and/or a portion of the packet and the MAC algorithm. That is, the receiving system may try to recreate the MAC of a packet using the pre-shared key, the MAC algorithm and/or a portion of the packet (e.g., pre-agreed upon serial number, content section, or the like of the packet). If the comparison between the determined MAC recreated by the receiving party meets the MAC of the packet received by the receiving party then packet is determined to be a wheat packet. Alternatively, when the determined MAC of a packet recreated by the receiving system fails to meet the MAC of the packet received by the receiving system, the packet is a chaff packet and is discarded.

It should be understood that any entity on the system can read any packet (e.g., the packet is not encrypted, hidden, or the like), such as the communication content, the receiving entity, the sending entity, and/or the routing; however, the receiving system can only identify the correct packets based on validating the signature attached to each packet (e.g., recreating the MAC signature).

As will be further described herein, in some embodiments of the invention, the chaff packets may be chaff packets generated (e.g., made up) by the sending computer systems or the security system 30. Alternatively, the chaff packets may be past or current wheat packets that were used for other communications outside of the present communication. By using unrelated wheat packets as the chaff packets, the systems are not required to generate chaff packets for the communications, which may reduce processing capacity and/or memory requirements, as well as increase processing speeds. The chaff packets may look like the wheat packets (e.g., correct format, have serial numbers, and have content, or the like), but the chaff packets have imitation signatures (e.g., MACs, or the like) that are not valid and cannot be recreated using the correct key and/or the correct algorithm (e.g., the pre-shared key and pre-shared algorithm).

In addition to sending chaff packets, the communications described herein may further include separating the packets (e.g., wheat and/or chaff packets) into multiple wheat packets (e.g., sub-wheat packets, or the like) which are each individually authenticated by adding the signature (e.g., MACs, or the like) to each of the sub-wheat packets. The separated sub-wheat packets may include serial numbers, which may function to both create the signature (e.g., the MACs), as well as allow the receiving system to reassemble the sub-wheat packets into the full wheat packet in the proper order. Consequently, the receiving system may use the signature of the multiple wheat packets (e.g., sub-wheat packets), as previously discussed herein, to identify the multiple wheat packets, remove the chaff packets with imitation signatures, and reassemble the multiple wheat packets (e.g., sub-wheat packets) into the full wheat packet in order to read the communication.

FIG. 3 provides a secure remote network environment 300, in which users 4 (e.g. a first user 4 a, a second user 4 b, or the like, such as a traveler) may try to access the network 2 (e.g., a home network 2), from a remote network, such as an unsecured network 3 (e.g., a first unsecured network 3, a second unsecured network 3). The users (e.g., a first user 4 a, a second user 4 b, or the like) may be traveling away from the home network 2, but may want to communicate with the home network 2. As such, the users 4 may try to communicate with the home network 2 directly from the unsecured networks 3 using the chaff packets as previously described herein. It should be understood, as will be described in further detail with respect to FIG. 4, the security systems and techniques previously described herein may be utilized in order to allow for secure communication from a user 4 (e.g., a first user 4 a, a second user 4 b, or the like) trying to communicate with the network 2 (e.g., home network) from another network (e.g., from a first unsecured network 3, a second unsecured network 3, or the like). That is, should a user 4 be planning on using networks that may be potentially unsecure (e.g., networks outside of the organization, networks of countries that do not allow encryption, or the like), then the user computer system 20 may be preloaded with the agent application to utilize one or more wheat packets and one or more chaff packets in order to send communications to the home network 2.

Moreover, users (e.g., a first user 4 a, a second user 4 b, or other users) operating remotely away from the home network 2 may not be able to control the routing of the communications through various networks back to the home network 2. As such, in addition to providing chaff packets for the communication, the secure remote network environment 300 may also utilize a remote secure network 5 through which all of the remote users 4 will connect to send communications back to the home network 2. The remote secure network 5, as will be described in further detail herein, may provide one or more relays (e.g., host receiving systems) through which communications may be routed. As such, the remote secure network 5 directs the one or more wheat packets and the one or more chaff packets through multiple relays (e.g., the same or different routings) in order to hide not only the communication using the chaff packets described herein, but from which networks the communication originated and to which networks the communications are to be routed, as will be discussed in further detail herein with respect to FIG. 4.

FIG. 4 provides a process flow for providing secure communications from remote networks 3 (e.g., potentially unsecured networks 3) outside of the network 2 (e.g., home network 2) without encryption of the packets used for the communication. As illustrated in block 110 of FIG. 4, each of the systems 20 of the users 4 that will be communicating with the network 2 (e.g., home network 2) from remote networks 3 may be updated with an agent application. The agent application may include a pre-shared key. Additionally, the agent application of each of the systems 20 that will communicate with the network 2 (e.g., home network 2) from a remote network 3 may also have a pre-shared algorithm or at least an indication to utilize a type of algorithm to create signatures for the communications. The pre-shared key and algorithm may be utilized by the users 4 to communicate with the home network 2 from a remote network 3.

As illustrated in block 120 of FIG. 4, a sending system creates a plurality of packets for a communication with other systems, such as a receiving system on a home network 2, while the sending system is using a remote network 3 (e.g., a potentially unsecured network 3). The packets may contain the content of the communication, packet information (e.g., packet identifiers, or the like), the systems to which the packets are to be sent (e.g., receiving entity, sending entity, and/or routing hosts), or other like information. The plurality of packets created by the sending system may comprise the one or more wheat packets and the one or more chaff packets, as previously described herein. The one or more wheat packets are the actual packets for the communication. As previously described herein, the wheat packets for a communication may be split up into a plurality of wheat packets in order to improve the security of the communication. The one or more chaff packets, as previously described herein, may comprise imitation packets that look like wheat packets, real packets for an unrelated communication (e.g., wheat packets for past or current unrelated communications on the network 2), or the like. When the agent application on the sending system creates the one or more chaff packets, the sending system may use a chaff packet algorithm (e.g., imitation packet generation, or the like). When the chaff packets are wheat packets from unrelated communications, the legitimate packets may be randomized (e.g., XORed, or the like with a log of network communications and/or salted using a pre-computed salt value, or the like).

Block 130 of FIG. 4 further illustrates that the sending system attaches a wheat signature to each of the one or more wheat packets. As previously described herein, the wheat signature may be created using the pre-shared key and the known algorithm (e.g., a pre-shared algorithm or pre-identified algorithm). Additionally, a section of the which packet, such as the content of the wheat packet, a serial number of the wheat packet, or the like, may also be used by the pre-shared algorithm to create the signature. Each signature created is attached to each wheat packet (e.g., different signatures are used on each wheat packet, or the like).

FIG. 4 further illustrates in block 140 that the one or more chaff signatures are attached to the one or more chaff packets. It should be understood that the chaff signatures may be imitation signatures that are similar to the wheat signatures (e.g., same length of characters, or the like) and are attached to the imitation chaff packets. Alternatively, the chaff signatures may comprise a modification of the original wheat signatures that are attached to the original wheat packets for other unrelated communications, which are now being used as chaff packets for the present communication. As described above with respect to the chaff packets themselves, the signature for the chaff packets may be randomized (e.g., XORed, or the like with a log of network communications and/or salted using a pre-computed salt value, or the like).

As illustrated in block 150 of FIG. 4, once the wheat packets and the chaff packets are created and/or identified from other sources and signed, the wheat packets and the chaff packets are sent to the one or more systems, such as the receiving systems on the home network 2. In some embodiments the wheat packets and the chaff packets are sent directly from the unsecured networks 3, on which the users 4 are located, to the home network 2 (e.g., in some embodiments using relays of other networks). Even though the packets are being sent without encryption and in plain text, the unsecured network 3 is unable to determine the communication because the unsecured network 3 (or a system on the unsecured network 3) is unable to determine what packets are the wheat packets and what packets are the chaff packets. That is, as will be described in further detail below with respect to block 195, the wheat packets and/or the chaff packets can only be determined by a system that has the pre-shared key, the known algorithm, and/or the correct section of the packet (e.g., content, serial number, or the like), such as a system on the home network 2 (e.g., authorized systems). That is, any system on the unsecured network 3, any systems on intermediary networks before the packets reach the home network 2, and/or any rogue systems on the home network 2, are unable to read the communication because these systems do not have the pre-shared key, algorithm (e.g., pre-shared algorithm) and/or the correct section of the packets. As such, it should be understood that the one or more packets may include the plain text of the communication, which is available for any system on any of the networks through which the packets are sent to read.

In some embodiments, it should be understood that the packets may be created within and/or routed through a secure remote network 5, as previously described with respect to FIG. 3 herein. That is, each user 4 (e.g., a first user 4 a, a second user 4 b, or the like) that is operating remotely may access a remote secure network 5 (e.g., log onto and create packets, send the packets through, or the like) and send the packets through the remote secure network 5 (e.g., operated by the organization that operates the home network 2, by a third-party, or the like). The remote secure network 5 randomizes the packets through various relays within the secure remote network 5, or accesses a network of secure remote networks 5, and then ultimately sends the packets to the home network 4 (e.g., the original destination).

With respect to the randomized routings, in some embodiments the initial relay in the remote secure network 5 may create the entire routing; however, in other embodiments each relay within the secure network 5 may be determined by each successive relay and/or each relay may randomly determine the next successive relay. In this way, each relay may only be aware of the previous relay from which the packets were received and the next relay to which the packets will be sent. Consequently, each relay, and thus each system trying to identify the routing, will not know the origination of the packets (e.g., the sending system) or the destination of the packets (e.g., the receiving system).

Consequently, in addition to using wheat packets and chaff packets, the secure remote network 5 may be utilized by each user 4 outside of the home network 2 in order to provide additional security around routing the packets from potential unsecure networks 3 to the home network 2. For example, since each user 4 is using the secure remote network 5, all of the packets being sent through the remote secure network 5 create additional wheat and chaff packets that make it difficult to identify the wheat from the chaff.

As illustrated by block 160 of FIG. 4, the receiving system receives the plurality of packets for the communication. The receiving system then determines a validated signature for each of the plurality of packets. That is, the receiving system replicates a received signature from each of the plurality of packets (e.g., a wheat signature attached to the wheat packet, a chaff signature attached to the chaff packet) by using the pre-shared key and algorithm and/or a portion of the packets (e.g., content, serial number, or the like) to determine what the received signature should be.

Block 170 of FIG. 4 further illustrates that when the validated signature meets the received signature from the packets, the packets are identified as wheat packets. That is, for example, when the recreated signature determined by the receiving system meets the received signature included with the packet, the packet is identified as a wheat packet. Alternatively, as illustrated by block 180 in FIG. 4, when the validated signature fails to meet the received signature from the packets, the packets are identified as chaff packets. That is, for example, when the recreated signature determined by the receiving system fails to meet the received signature included with the packets, the packet is identified as a chaff packet. When the packets are identified by the receiving system as chaff packets, the chaff packets are discarded by the receiving system.

Block 190 of FIG. 4 illustrates that the receiving system reads the one or more wheat packets to determine the communication. In some embodiments when a plurality of wheat packets (e.g., sub-packets) are identified, the receiving system reassembles the plurality of wheat packets together to form the communication. In some embodiments the wheat packets may have wheat packet identifiers (e.g., sequential characters, or the like) that may be used to reassemble the wheat packets. Alternatively, or additionally, the pre-shared key and/or the algorithm may be used to determine the order of the plurality of packets in order to read the communication.

FIG. 4 further illustrates in block 195 that the security system network environment 300 described herein prevents the networks and/or systems thereof, such as the unsecured networks 3 from reading any communications made by the users 4 (e.g., travelers) using the user computer systems 20 that are being sent back to the home network 2. It should be understood that when users 4 are operating on networks in some areas (e.g., some countries, or within some businesses), the networks may be unsecured networks 3. For example, some unsecured networks 3 may require the users 4 and/or user computer systems 20 to provide the unsecure network 3 (or systems operating the unsecure network 3) any encryption keys that are traditionally used to encrypt communications, and in particular, encrypt the text of the packets used to send the communications. However, since the packets are being sent in clear text, any encryption key provided to the unsecured network 3 and/or the system thereof, is useless. As such, without the pre-shared key and the algorithm the unsecured network 3 and/or any system operating thereon is unable to determine what packets are wheat packets and what packets are chaff packets. Furthermore, it should be understood that any other rogue system trying to identify the communication as it is being sent from the unsecured network 3 to the home network 2 would be unable to determine the correct communication because it also does not have the ability to determine the wheat packets from the chaff packets. Moreover, when the remote secure network 3 is utilized, the routing of the packets and/or the IP addresses of the sending system, receiving system, and/or relays for the packets may also be secured through the use of randomized routings. Consequently, the use of the remote secure network 3 provides additional security to the communication.

FIG. 5 illustrates a process for obfuscating a sending entity, a receiving entity, and/or the routing of the of a communication across networks and/or relays. As such, alternatively or in addition to obfuscating the details of a communication using wheat packets and chaff packets as previously described herein, FIG. 5 provides a process for providing additional security measures. That is, while a potential misappropriator may not be able to determine the subject matter of a particular communication, such as if the process described with respect to FIG. 4 is implemented, the potential misappropriator may be able to determine information about the communication based on determining the identity of the sending entity, the receiving entity, and/or the routing of the communication. For example, some governments, individuals, organizations or the like may track the sending entities, receiving entities, routings, locations of forgoing, network from which and to which the communications are being sent, or the like in order to identity potential information related to the communication. Examples, may include monitoring the foregoing information in order to identify potential inside stock market information (e.g., communications between organizations that indicate potential mergers, joint development), political dissidents (e.g., governments monitor protestors, or the like), identify information that may aid in determining user account information (e.g., individuals gaining information that could be used to access customer accounts), or the like.

Block 210 of FIG. 5 illustrates that if a user is planning on traveling or otherwise planning on sending communications within a network or across networks a pre-shared sky and algorithm may be provided to the user for providing security for communications. For example, such a user plan on using a second network (e.g., an unsecured network) to communicate with a first network (e.g., a home network), the first network or a system thereof may provide a pre-shared key and/or a pre-shared algorithm for the user computer system 20 to utilize when communicating with the first network, as previously discussed with respect to block 110 of FIG. 4. As such, the agent application previously described herein may include a pre-shared key that is used to create the wheat signatures for the wheat packets and/or potions thereof. Additionally, the agent application of each of the systems 20 that will communicate with the network 2 (e.g., home network 2) from a remote network 3 may also have a pre-shared algorithm or at least an indication to utilize a type of algorithm to create signatures for the communications. The pre-shared key and algorithm may be utilized by the users 4 to communicate with the home network 2 from a remote network 3. Alternatively, or additionally, the process described with respect to FIG. 5 may be utilized to within a single network 2 (e.g., between systems on the first network).

FIG. 5 further illustrates in block 220 that the sending system creates a plurality of packets for a communication with other systems. For example, the plurality of packets may be created for a communication between systems on a network (e.g., on a home network). In other examples, the sending system creates a plurality of packets for a communication with a receiving system on a home network 2, while the sending system is using a remote network 3 (e.g., a potentially unsecured network 3). The packets may contain the content of the communication, packet information (e.g., packet identifiers, or the like), the receiving entity (e.g., the receiving system) to which the packets are to be sent, the sending entity (e.g., the sending system) which is sending the communication, the routing of communication (e.g., the one or more hosts through which the communication will be routed), or other like information. The plurality of packets created by the sending system may comprise the one or more wheat packets and the one or more chaff packets, as previously described herein. The one or more wheat packets are the actual packets for the communication and may include a data packet portion, an IP packet portion, and a routing packet portion. The data packet portion may be wrapped within the IP packet portion, which may be wrapped within the routing packet portion. Consequently, as will be discussed in further detail herein with respect to blocks 230 to 234, it should be understood that one or more of any of the fields within the data packet portion, the IP packet portion, and the routing packet portion may be obfuscated without encryption by utilizing wheat packets that contain the actual information and chaff packets that contain the imitation information.

As previously described herein, the wheat packets for a communication may be split up into a plurality of wheat packets in order to improve the security of the communication. The one or more chaff packets, as previously described herein, may comprise imitation packets that look like wheat packets, real packets for an unrelated communication (e.g., wheat packets for past or current unrelated communications on the network 2), or the like. When the agent application on the sending system creates the one or more chaff packets, the sending system may use a chaff packet algorithm (e.g., imitation packet generation, or the like). When the chaff packets are wheat packets from unrelated communications, the legitimate packets may be randomized (e.g., XORed, or the like with a log of network communications and/or salted using a pre-computed salt value, or the like).

Block 230 of FIG. 5 illustrates that the plurality of datagram packets are created, which may include one or more wheat datagram packets and one or more chaff datagram packets. FIG. 6 illustrates one example of a datagram packet 300 (e.g., a TCP datagram, or the like); however, it should be understood that any type of datagram packet may be utilized and the illustrated datagram packet 300 is for illustrative purposes only. As illustrated in FIG. 6, the datagram packet 300 may include a segment header section 310 and a datagram data section 350. The segment header 310 may include some mandatory fields (e.g., 10 mandatory fields) and an extension section that is optional. The segment header 310 includes the source port 312 (e.g., identification of the source); destination port 314 (e.g., identification of the destination); a sequence number 316 (e.g., sequence for multiple packets); acknowledgment number 318 (e.g., acknowledgment of the sequence numbers by each end); data offset 320 (e.g., size of header); reserved 322 (e.g., reserved for use in the future); flags 324 (e.g., 9 separate 1-bit flags which may or may not be used); window size 326 (e.g., provides size of the packet segment); checksum 328 (e.g., used for error checking of the segment header 310, the data section 350, and/or the IP packet header (described below)); pointer 330 (e.g., offset of the sequence number indicating the an urgent data byte); and/or options 332 (e.g., optional information). The one or more wheat datagram packets will contain the actual datagram packet and the one or more chaff datagram packets may be created or may be real unrelated datagram packets. The chaff datagram packets may be used in order to make it difficult for anyone (e.g., a potential misappropriator) to identify the wheat datagram packet from the chaff datagram packets without being able to identify the verified signature).

FIG. 5 further illustrates in block 232 that the plurality of IP packets are created, which may include one or more wheat IP packets and one or more chaff IP packets. FIG. 7 illustrates on embodiment of an IP packet 400; however, it should be understood that any type of IP packet may be utilized, and the illustrated IP packet 400 is for illustrative purposes only. As illustrated in FIG. 7, the IP packet 400 may also have an IP header section 410 and IP data section 450. The IP header section 410 may comprise a version 412 (e.g., version of the packet); an internet header length (IHL) 414 (e.g., indicates the size of the header); a differentiated services code point (DSCP) 416 (e.g., specifies the services related to the communication); an explicit congestion notification (ECN) 418 (e.g., allows notification of network congestion without dropping packets); a total length 420 (e.g., defines the entire packet length); an identification 422 (e.g., uniquely identifying the group of fragments of a single IP packet); flags 424 (e.g., used to control or identify fragments); fragment offset 426 (e.g., specifies the offset of a fragment relative to the original IP packet); time to live (TTL) 428 (e.g., prevents persisting IP packets); protocol 430 (e.g., defines the protocol used for the data in the IP packet); header checksum 432 (e.g., error-checking the header); source address 434 (e.g., IP address of the sender); destination address 436 (e.g., IP address of the receiver); and options 438 (e.g., for providing additional information). The one or more wheat IP packets will contain the actual IP packets and the one or more chaff IP packets may be created or may be real unrelated IP packets may be used. The chaff IP packets may be used in order to make it difficult for anyone (e.g., a potential misappropriator) to identify the wheat IP packet from the chaff datagram packet without being able to identify the verified signature.

Block 234 of FIG. 5 illustrates that the plurality of routing packets are created, which may include one or more wheat routing packets and one or more chaff routing packets. FIG. 8 illustrates one example of a routing packet 500; however, it should be understood that any type of routing packet may be utilized, and the illustrated routing packet 400 is for illustrative purposes only. The routing packet 500 may include a routing header section 510 and a routing data section 550. The routing header section 510 may include a marker 512 (e.g., provides compatibility); a length 514 (e.g., provides total length of the message); and a type 516 (e.g., includes type of message). The routing data section 550 of the routing packet establishes how to rout the packet between two or more locations. For example, the entire routing path, a portion of the routing path, or a single routing path between two points for the packet may be included in the routing packet 500. That is, the routing path from the sending system to the receiving system may be provided, or a portion may be provided, and each relay (e.g., host system) determines the next routing of the packets. In some embodiments, the hosts may be able to determine the entire routing of the communication, while in other embodiments the each host may only be able to determine the next host to which to route the communication (e.g., the packets thereof).

It should be understood that depending on a level of security a sending system and/or received system would like for a communication, the sending system may use wheat and chaff packet portions for one or more of the datagram packet, the IP packet, and/or the routing packet. For example, the sending system may create a wheat datagram packet with the actual information for the communication. The chaff datagram packet may include imitation information for any information in the chaff datagram segment header 310, including the source 312, the destination 314, and/or the like or the in the datagram data 350 itself. The sending system may also create a wheat IP packet with the actual information for the communication. Moreover, the chaff IP packet may include imitation information for any of the information in the IP header 410, such as the source IP address 434, the destination IP address 436, or the like, or the IP packet data packet 450. The sending system may also create a wheat routing packet with the actual information for the communication. Moreover, the chaff routing packet may include imitation information for any of the information in the routing header 510 and/or the routing data 550. For example, the chaff packets may change the sending systems, the receiving systems, the hosts within the routing, the path length (e.g., short hop length, longer hop length, or the like), length of connections, or the like.

It should be understood that the datagram packet 300, the IP packet 400, and/or the routing packet 500 are operatively coupled together. For example, the datagram packet 300 is located within the IP packet 400 (e.g., the datagram packet is located within the envelope of the IP packet 400) and the IP packet 400 is located within the routing packet 500 (e.g., the IP packet 400 is located within the envelope of the routing packet 500).

FIG. 5 further illustrates in block 240 that the wheat packet portions are signed with a wheat signature while the chaff packets are assigned a chaff signature (e.g., created and attached to the chaff packets, a modified signature of an old packet is created, a old signature of a packet is utilized, or the like). It should be understood that any number of the fields within the datagram packet 300, the IP packet 400, and/or the routing packet 500 may be signed with a wheat signature (e.g., for the packets that have the actual information) or a chaff signature (e.g., for the packets that have the imitation information). In some embodiments the datagram packet 300 may include the signature (e.g., wheat signature or chaff signature), such as within the sequence number 316, the acknowledgment 318, the flags 324, the checksum 328, or the like. As such, only the entities that are able to determine the verified signature, for example using the key (e.g., pre-shared key) and/or the algorithm (e.g., pre-shared algorithm), are able to determine a wheat datagram packet from a chaff datagram packet. Alternatively, or additionally, the IP packet 400 may include the signature (e.g., wheat signature or chaff signature), such as within the identification 422, the flags 424, the header checksum 432, or the like. Consequently, only the systems that can determine a validate signature (e.g., using the key and/or algorithm) are able to determine a wheat IP packet from a chaff datagram packet. Alternatively, or additionally, the routing packet 500 may include the signature (e.g., wheat signature or chaff signature), such as in the marker 512, the routing data 550 itself, or the like. As such, only the systems that can determine the validated signature (e.g., have the key and/or algorithm) are able to determine the wheat routing packets from the chaff routing packets.

After the one or more wheat packets (e.g., each including the wheat datagram packet, the wheat IP packet, and/or the wheat routing packet) are created, and/or the one or more chaff packets (e.g., each including the chaff datagram packet, the chaff IP packet, and/or the chaff routing packet) are identified (e.g., created, captured, or the like), the plurality of packets are routed. For example, between systems within a network, or from the remote network (e.g., the unsecured network) to the one or more relays (e.g., one or more hosts for routing between one or more intermediate networks) and to the destination receiving system on the home network.

FIG. 5 illustrates in block 250 that the plurality of packets are sent from the sending system to the receiving system directly within the first network or between networks back to the home network through one or more relays. For example, as previously discussed with respect to FIG. 4, the packets may be sent through the remote secure network 5. In some embodiments each of the relays (e.g., hosts), within the remote secure network 5 through which the packets are routed need to recreate a validated signature (e.g., using the pre-shared key and/or algorithm) in order to determine what packets are the wheat packets and what packets are the chaff packets, and how the packets should be routed back to the home network 2. In some embodiments of the invention, each of the relays (e.g., hosts) do not need to determine a validated signature (e.g., using the pre-shared key and/or the pre-shared algorithm) since only the sending system and/or the receiving system, and/or a portion of the routing is being obfuscated using the wheat and chaff packets.

Moreover, block 260 of FIG. 5 illustrates that each system that accesses the packets determines a validated signature for each of the packets. For example, each relay, such as one or more hosts systems, used to route the communication between systems and/or networks determines a validated signature for each of the plurality of packets (e.g., from sections of the datagram packet 300, the IP packet 400, and/or the routing packet 500). In other examples, as previously discussed, the receiving system on the home network determines a validated signature from each of the plurality of the packets or portions thereof (e.g., from sections of the datagram packet 300, the IP packet 400, and/or the routing packet 500) in order to determine what packets are the wheat packets and what packets are the chaff packets. In other examples, should any system be unable to recreate a validated signature (e.g., should any system not have the pre-shared key and/or pre-shared algorithm), such as a potential misappropriator, the system would be not able to determine what entity was the sending system, what entity was the receiving system, the routing information for the communication, and/or the communication content.

Block 270 of FIG. 5 further illustrates that when the validated signature meets the received signature from the packets or portions of the packets, the packets are identified as wheat packets. That is, for example, when the recreated signature determined by the host system meets the received signature included withing the packets or portions thereof (e.g., the portions of the datagram packet 300, the IP packet 400, and/or the routing packet 500), the packet is identified as a wheat packet. Alternatively, as illustrated by block 280 in FIG. 5, when the validated signature fails to meet the received signature from the packets or the portions thereof (e.g., the portions of the datagram packet 300, the IP packet 400, and/or the routing packet 500), the packets are identified as chaff packets. That is, for example, when the recreated signature determined by the host system fails to meet the received signature included with the packets, the packet is identified as a chaff packet. When the packets are identified by the host system as chaff packets, the chaff packets are discarded by the host system. However, in some embodiments it should be understood that when the host system identifies chaff packets, instead of discarding the chaff packets, the chaff packets may be sent onto the next host system in the routing (e.g., the host in the routing). Alternatively, each of the host systems may utilize (e.g., create or identify) new chaff packets or portions thereof (e.g., the datagram packet 300, the IP packet 400, and/or the routing packet 500), as previously described herein, for routing the what packets and chaff packets to the next host system within the routing.

As previously discussed with respect to block 190 of FIG. 4, when the communication has been obfuscated using wheat packets and chaff packets, when the packets reach the receiving system that is the destination, the receiving system identifies the one or more wheat packets in order to determine the communication from the sending system. In some embodiments when a plurality of wheat packets (e.g., sub-packets) are identified, the receiving system reassembles the plurality of wheat packets together to form the communication. In some embodiments the wheat packets may have wheat packet identifiers (e.g., sequential characters, or the like) that may be used to reassemble the wheat packets. Alternatively, or additionally, the pre-shared key and/or the algorithm may be used to determine the order of the plurality of packets in order to read the communication.

As previously discussed with respect to block 195 in FIG. 4 the security system network environment 300 described herein not only prevents the networks and/or systems thereof, such as the unsecured networks 3, from determining what is the correct content being transmitted by the packets (e.g., because the other networks and/or systems are not able to determine what packets are wheat packets and what packets are chaff packets), but the process of FIG. 5 illustrates how the sending system, the destination system, and/or the routing of the packets may be obfuscated such that any system that is unable to determine a validated signature is unable to determine the sending system, the destination system, and/or the routing of the packets.

It should be understood that even when the content of a communication is encrypted, or otherwise obfuscated (e.g., as previously discussed with respect to FIG. 4), information may be still be determined about the communication from determining the identity of the sending entity, the receiving entity, and/or the routing the communication (e.g., low number hop, large number of hops, patterns of the routings, locations from which and to which the communications are routed, or the like). That is, while a potential misappropriator may not be able to determine the subject matter of a particular communication, the potential misappropriator may be able to determine information about the communication based on determining the identity of the sending entity, the receiving entity, and/or the routing of the communication. For example, some governments, individuals, organizations or the like may track the sending entities, receiving entities, routings, locations of forgoing, network from which and to which the communications are being sent, or the like in order to identity potential information related to the communication. Examples, may include monitoring the foregoing information in order to identify potential inside stock market information (e.g., communications between organizations that indicate potential mergers, joint development), political dissidents (e.g., governments monitor protestors, or the like), identify information that may aid in determining user account information (e.g., individuals gaining information that could be used to access customer accounts), or the like. As such, the present invention provide obfuscation of a sending entity, a receiving entity, and/or the routing of the of a communication across networks and/or relays.

The present disclosure provides an improved way for systems to communicate back to a home network 2 from an unsecured network 3 without encrypting the content of the packets being sent for the communication. Moreover, the present disclosure provides an improved way to prevent systems on an unsecure network, systems on intermediate networks through which the communication is sent, and/or a rogue system on a home network 2 from determining the actual communication, receiving system, sending system, and routing without having to encrypt the communication. The present disclosure improves the processing capacity, the memory, and the processing speeds typically required when each of the packets for a communication requires encryption. That is, typical encryption processes require more processing capacity and memory, and more processing time to encrypt and decrypt each communication over networks.

It should be understood, that the systems described herein may be configured to establish a communication link (e.g., electronic link, or the like) with each other in order to accomplish the steps of the processes described herein. The link may be an internal link within the same entity (e.g., within the same organization) or a link with the other entity systems. In some embodiments, the one or more systems may be configured for selectively monitoring the resource usage and availability. These feeds of resource usage and availability may be provided via wireless network path portions through the Internet. When the systems are not providing data, transforming data, transmitting the data, and/or the like, the systems need not be transmitting data over the Internet, although it could be. The systems and associated data for each of the systems may be made continuously available, however, continuously available does not necessarily mean that the systems actually continuously generate data, but that systems are continuously available to perform actions associated with the systems in real-time (i.e., within a few seconds, or the like) of receiving a request for it. In any case, the systems are continuously available to perform actions with respect to the data, in some cases in digitized data in Internet Protocol (IP) packet format. In response to continuously monitoring the real-time data feeds from the various systems, the systems may be configured to update activities associated with the systems, as described herein.

Moreover, it should be understood that the process flows described herein include transforming the data from the different systems (e.g., internally or externally) from the data format of the various systems to a data format for display on other systems. There are many ways in which data is converted within the computer environment. This may be seamless, as in the case of upgrading to a newer version of a computer program. Alternatively, the conversion may require processing by the use of a special conversion program, or it may involve a complex process of going through intermediary stages, or involving complex “exporting” and “importing” procedures, which may be converting to and from a tab-delimited or comma-separated text file. In some cases, a program may recognize several data file formats at the data input stage and then is also capable of storing the output data in a number of different formats. Such a program may be used to convert a file format. If the source format or target format is not recognized, then at times a third program may be available which permits the conversion to an intermediate format, which can then be reformatted.
